Is that the USB version?

Ensure that you connect the mic before you launch Audacity.
You should then see a USB device listed in the recording tab of the device toolbar.

If you install the "Channel Mixer" plug-in (https://wiki.audacityteam.org/wiki/Nyqu ... nnel_Mixer), you can duplicate one channel into the other channel, the use the "stereo to mono" macro command.

The only thing that comes to mind at the moment, is that perhaps there is a poor connection between the UCA202 and the computer (such as a bad lead, wobbly socket, or similar), causing the connection to be intermittent, and so creating new instances of the drivers each time it reconnects. Are you ab...

I don't understand why you have all of those "Microphone(?-USB CODEC)" devices. When I connect a UCA202 to my Windows 10 laptop, it shows up as exactly one device, and is called "Microphone (USB Audio CODEC )". Do you have other USB devices connected to your computer? Is the UCA2...

Something else that's odd: after it doesn't open, if I click it again I get this message: "The system has detected that another copy of Audacity is running. I think I misinterpreted what you were saying here. Did that message only come up the second time that you try to launch Audacity? If so,...

My id14 records beautifully, but I'm not able to hear what I'm saying into the mic via the headphones.

Plug your headphones into the id14.

I don't know if it even has a name

I'd call it a "unipolar pulse train".

I don't understand why you insist that a uniformly random sound generator is not a "true white noise generator". A uniformly random signal is white noise.

Because he likes to argue.

I wanted to start with simple pure sine waves and show additive synthesis Audacity has a scripting language built in called "Nyquist". It is very good for this sort of thing. Here's an example script that sums the first 8 harmonics of a "square" wave: ;version 4 (setf harmonics ...

but it doesnt shown the beat frequency you get from mod| B-A| No, it won't do, because the FFT resolves the waveform into A and B. You need to approach it the other way round: Generate a "Square, no alias" waveform at 100 Hz. It looks like this when you zoom in: firsttrack000.png If I zoo...

I agree that a simpler interface would be nice, but achieving the best noise reduction with minimum damage to the remaining audio, requires compromises and judgement calls. How "bad" the noise sounds is highly subjective. Computers are not good at making subjective decisions, hence the nee...
